STROKEAHA: September 12, 2013 The American Heart Association in its 2013 Stroke Statistics Update1 reports the annual direct and indirect costs of stroke in the United States to be $62.7 billion, with 15% to 30% of stroke survivors being permanently disabled and 20% requiring institutional care at 3 months after stroke. Rapid recognition and accurate diagnosis are […]
STROKEAHA: December 5, 2013 Background and Purpose—Whether transient global amnesia (TGA) represents an arterial insult that heralds ischemic stroke remains unclear. Therefore, we examined stroke risk after TGA in a population-based cohort. Methods—After performing chart review at our institution to validate the International Classification of Diseases, 9th Edition, Clinical Modification diagnosis code for TGA, we used […]
STROKEAHA: December 3, 2013 Background and Purpose—Arterial spin labeling (ASL) is a perfusion magnetic resonance imaging (MRI) technique that does not require contrast administration and thus may be more practical in hyperacute stroke than susceptibility-weighted bolus-tracking perfusion-weighted imaging (PWI). However, a threshold for ASL measurement of the ischemic penumbra needs to be determined. Read More
STROKEAHA: November 26, 2013 Expanding the Concept of Poststroke Disability Background and Purpose—Limitations in essential daily activities are common among older adults after stroke, but little is known about restrictions in their ability to participate in valued social activities. We sought to broaden our understanding of disability after stroke by characterizing poststroke participation restrictions and investigating […]
The Lancet, Early Online Publication, 22 November 2013 Body-mass index (BMI) and diabetes have increased worldwide, whereas global average blood pressure and cholesterol have decreased or remained unchanged in the past three decades. We quantified how much of the effects of BMI on coronary heart disease and stroke are mediated through blood pressure, cholesterol, and […]
STROKEAHA: November 12, 2013 Background and Purpose—Many patients with an acute stroke live in areas without ready access to a Primary or Comprehensive Stroke Center. The formation of care facilities that meet the needs of these patients might improve their care and outcomes and guide them and emergency responders to such centers within a stroke system […]
